- pumps are often found as part of medical apparatus or as separate units connected to medical apparatus.
- rinsing fluid into the surgical area or a body cavity comprising the operating area by means of a pump.
- the body cavity is thereby filled and expanded by the rinsing liquid so that the operating area for the surgeon, for example.

- the detection module 8 is designed, starting from the height of the operating table 20 at the time at which the pump pressure of the pump unit 2 was initially set to the user interface 7, based on the queried output information, the height difference of the height adjustment - ie the difference in height of at any time and the time ⁇ point, the pump pressure of the pump unit 2, a ⁇ was provided initial Opera- tion diagram 20 - to be determined.
- the height difference can also be determined with respect to a specified reference altitude.
- the control unit 6 is designed to adjust the pump pressure ⁇ the pump unit 2 in response to the height difference determined by the detection module 8, so that the pressure of the rinsing liquid in the operating area 5 despite height adjustment of the operating table 20 remains constant.
- ⁇ is the required change in the pump pressure and Ah is the height difference determined by the detection module 8.
- the term 10 - (corresponds) is a
- the correction factor a is 1 in the illustrated embodiment.
- FIG. 2 shows a second embodiment of an inventive arrangement 100 comprising a second embodiment of a pump device 1 according to the invention and a height-adjustable operating table 50 is shown.
- the arrangement 100 and the pump device 1 from FIG. 2 largely correspond to those from FIG. 1, for which reason reference is made to the statements there. In the following, only the differences between the exemplary embodiments according to FIGS. 1 and 2 will be discussed.
- the Erfas ⁇ sungsaku 8 is not with a control electronics (24;., See Figure 1, not shown in Figure 2) of the operating table 20 is connected. Rather, the pump device 1 also comprises a telemetry unit 10 comprising a telemetry transmitter 11 and a reference module 12.
- the telemetry transmitter 11 is designed to determine the distance between it and the reference module 12 via a distance measuring unit.
- the distance measurement is carried out by a field strength measurement from the reference module 12 generated electromagnetic field by the distance measuring unit.
- the telemetry transmitter 11 Since the telemetry transmitter 11 is arranged on the height-adjustable part 22 of the operating table 20 and the reference module 12 at the base 23 of the operating table 20, can be determined the currently selected amount of Operations ⁇ table 20 from the determined distance between the telemetry transmitter 11 and reference module 12th
- the arrangement of telemetry transmitter 11 and reference module 12 can also be interchanged.
- the telemetry transmitter 11 has a radio antenna 13 which cooperates with a radio antenna 9 arranged on the detection module 8 in order to exchange information between the telemetry transmitter 11 and the detection module 8.
- the telemetry transmitter 11 can thereby provide various output information that the absolute level of the operating table 20 are immediacy ⁇ bar comparable in Steue ⁇ approximately electronics 24 of the same embodiment in particular with the height adjustment signal of the control electronics 24 of the first embodiment according to FIG 1 and to output information concerning.
- the telemetry transmitter 11 may monitor the absolute altitude change or may include an acceleration sensor that picks up any accelerations in the vertical direction.
- the detection module 8 of the pump device 1 likewise has two operating modes that can be set via the user interface 7.
- the operating modes correspond to those of the first embodiment, wherein the output information come only from the telemetry unit 10 and not from the control electronics 24 of the operating table 20. Reference is therefore made to the above statements.
- 3 shows a variant of the embodiment of Figure 2 is shown.
- the voltage measurement unit of the Entfer ⁇ arranged on the height-adjustable part 22 of the operating table 20 telemetry transmitter 11 measures the distance to both the floor 90 and the ceiling 91 of the Ope ⁇ rationssaals. The distance measurement takes place via a running time measurement of an electromagnetic wave outside the visible spectrum.
- the telemetry transmitter 11 transmits both distances as output information to the detection module 8.
- the detection module 8 performs a validity check of the distances by comparing the sum of the distances with the distance between the floor 90 and the ceiling 91. If the said sum corresponds to this distance, the measured distances are valid and can be further processed according to the invention. Diesbezüg ⁇ Lich is made to the description of FIG. 2
- a light source 15 which forms ⁇ out as a laser and is associated with the acquisition module.
- the light source projects a ⁇ calibration plane 16 on the lying on the operating table 20 patients.
- the calibration plane 16 is projected such that in the initial height adjustment of the operating table 20, the environment of the operating area 5 - ie the area around the insertion point of the endoscope 4 - is free of projections of the light element 15, at a height adjustment of Operating table 20 down the projection, however, in this environment, which is typically in the field of view of the Opera ⁇ teurs wanders.
